CI867 Redundancy when ethernet break
Hi every one!
I have 2 problems about CI867 with redundancy config. Please help me to solver it:
If I unplug cable from Ch1(10/100M) port of primary CI867, the system automatically switch over to backup CI867. It work fine!
But between primary CI867 and Modbus slave device have one switch, when I unplug cable from Modbus slave device port, the primary CI867 can not detect disconnect event from Modbus slave device!
My question: How to make CI867 can detect event when unplug cable from Modbus slave device port and automatically switch over in this case.
How to manual switch over CI867 redundancy from HMI and from controller application?
1. Works as designed, see below:
In order for this to work, your slave device must detect the cable break.
I have seen solutions where both CI867s are active, they work in parallel and redundancy is implemented with code.
2. In Control Builder Online mode, right-click on the CI867 module, go to redundancy and then "Switch Primary".
Hope this helps (:
